Steering column of vehicle

Abstract

Disclosed is steering column of a vehicle including: a plate bracket that surrounds a distance bracket that is coupled to an outer column, has tilt slits on opposite sides thereof, and has a locking gear in any one of opposite surfaces of the tilt slits; an adjusting bolt that has a body passing through the tilt slits and the distance bracket from a head thereof, and in which a fixed cam and an actuating cam are coupled to a side of the body opposite to the head in order to press or release opposite sides of the plate bracket; a locking member into which the adjusting bolt is inserted and which is coupled to or released from the locking gear; and a resilient body that is coupled to the locking member and the adjusting bolt in order to apply a resilient restoring force to the locking member.

What is claimed is: 
     
       1. A steering column of a vehicle, comprising:
 a plate bracket that surrounds a distance bracket that is coupled to an outer column, has tilt slits on opposite sides thereof, and has a locking gear in any one of opposite surfaces of the tilt slits; 
 an adjusting bolt that has a body passing through the tilt slits and the distance bracket from a head thereof, and in which a fixed cam and an actuating cam are coupled to a side of the body opposite to the head in order to press or release opposite sides of the plate bracket; 
 a locking member into which the adjusting bolt is inserted and which is coupled to or released from the locking gear; and 
 a resilient body that is coupled to the locking member and the adjusting bolt in order to apply a resilient restoring force to the locking member in a rotational direction of the adjusting bolt, 
 wherein one side of the resilient body is in contact with the locking member and another side of the resilient body is in contact with the distance bracket, and 
 wherein a stepped accommodation part is formed in a through-hole of the distance bracket to accommodate the resilient body. 
 
     
     
       2. The steering column of  claim 1 , wherein a locking boss protrudes from one side of an outer peripheral surface of the locking member in a rotational direction towards the locking gear. 
     
     
       3. The steering column of  claim 1 , wherein a central portion of the resilient body surrounds an outer peripheral surface of the adjusting bolt and opposite ends of the resilient body are coupled to the locking member and the adjusting bolt, respectively. 
     
     
       4. The steering column of  claim 1 , wherein an assembly hole is formed in the locking member, and a first fixed part is formed in the resilient body by bending one end of the resilient body to be coupled to the assembly hole. 
     
     
       5. The steering column of  claim 4 , wherein a planar part, an outer peripheral surface of which is recessed, is formed in the body of the adjusting bolt, and a second fixed part, which is supported by and fixed to the planar part, is formed in the resilient body by bending an opposite end of the resilient body. 
     
     
       6. The steering column of  claim 5 , wherein a coupling part corresponding to the planar part protrudes from an inner peripheral surface of the actuating cam so that the adjusting bolt is rotated when the actuating cam is rotated. 
     
     
       7. The steering column of  claim 4 , wherein a coupling hole is formed in the body of the adjusting bolt, and a second fixed part, an end of which is fixedly coupled to the coupling hole, is formed in the resilient body. 
     
     
       8. The steering column of  claim 1 , wherein the locking member and the resilient body are accommodated in the tilt slits of the plate bracket. 
     
     
       9. The steering column of  claim 1 , wherein each of the locking member and the resilient body is provided in pair inside the tilt slits, such that a first pair of the locking member and the resilient body is coupled to the head of the adjusting bolt and a second pair of the locking member and the resilient body is coupled to the fixed cam.
